The energy loss of a 3-dimensional harmonic oscillator due to the quadrupole radiation in quadratic f (R) gravity is calculated.

Because of the everyday use of power generators in Iraq, which exist in residential neighborhoods, it is necessary to study the impact on soils and plants surrounding areas of those generators. Lead is one the most heavy ...

We study the eigenenergies and eigenfunctions of the ground and first excited states (GFES) of an electron strongly coupled to the LO-phonon in an asymmetry quantum dot (AQD) under an applied electric field by using a ...

The fabrication of a non-doped red organic light-emitting device (OLED) has been developed using naturally occurring curcumin as an emissive layer of OLED. In this research, the electroluminescent spectrum (EL) of curcumin ...

In this paper , the quintic B-spline collocation scheme is employed to approximate numerical solution of the KdV-like Rosenau equation . This scheme is based on the Crank-Nicolson formulation for time integration and quintic ...

This paper aims to study a generalized double sinh-Gordon equation, which appears in several physical phenomena such as integrable quantum field theory, kink dynamics and fluid dynamics. Lie symmetry analysis together with ...

In this paper the synthesis of some new polyaromatic monocyclic β-lactams has been reported. These cycloadducts have been synthesized by the [2+2] ketene-imine cycloaddition reaction known as the Staudinger reaction. All ...

The effects of conduction band nonparabolicity, aluminum concentration and external electric field on the charge density and binding energy of an on-center hydrogenic donor impurity in a spherical quantum dot which is ...

The complex-step derivative approximation is applied to compute numerical derivatives. In this study, we propose a new formula of fractional complex-step method utilizing Jumarie definition. Based on this method, we ...
